A method and an arrangement for measuring the smoothness of grains

Abstract

The present invention relates to a method and an arrangement for measuring the smoothness of grains. In one embodiment, the arrangement includes a channel for supplying grains, especially rice grains, an obstacle arranged at the channel to slow down grains falling on the obstacle, so that the flow of grains forms a heap on the obstacle and an image capturing device placed facing the obstacle. The image capturing device is arranged to capture an image of the heap, where the area under the curve of the captured heap image indicates the degree of smoothness of the grains or the course of the curve of the captured heap image indicates the degree of smoothness of the grains.

Description

technical field [0001] The invention relates to a device for measuring the smoothness of grain and a method for determining the smoothness of grain. Background technique [0002] The smoothness of polished grains, such as rice, is an important quality parameter in the grain grinding industry. The smooth surface obtained is indicative of the quality of the grind obtained. Evaluation of smoothness is usually done manually based on touch and feel, and thus is a subjective observation of each evaluator. [0003] In general, it is difficult to judge the quality of a wide variety of grains, especially paddy, eg, assessed as high quality or low quality. The assessment of quality, ie, the smoothness of the paddy, is determined based on personal judgment, which requires at least two samples for comparison. In the absence of any method backed by a scientific standpoint, the rice thus produced will often be irregular in quality, and this is often the object of concern. [0004] The...
